This invention relates to improvements in sealing/rings or members of the character employed for removably securing the heads or covers to containers and the like.

In practice, greases oils, paints and other substances are generally stored and/or transportedl moval ofthe ring, and do not permit ofrepeated use.

. It is a prime vide a snap-on sealing ring for the 4purpose specified whichis of resilient construction, and includes cooperating means on the free ends thereof for intertting and interlocking engagement to prevent disengagement of said ring byA stresses either radially or circumferentlally of the container.

It is' a further object to provide in vsuch a construction, snap-on means adapted to readily interflt and interlock and of substantial design, possessing a high degree of durability which renders said means t for repeated and continued L use without accidental disengagement or breakage.

2 Additional objectsand advantages will become apparent from .the following description taken in connection with the accompanying drawings, wherein: I 40 L Fig. 1 -is/a perspective collective view of the free vends 7of a snap-on sealing ring constructed in accordance with my invention;

Fig.'9. a cross-section taken on the line IX--IX loi Fig. 8.

Referring to the drawings, A designates a co/ny tainer known in the art as a steel drum, formed at its open end or top with a circumferential rolled portion or bead 2. A metal head or cover 3 is provided for closingthe drum, said head being removable and having an annular grooved or channelled rim 4 for engaging the rolled portion or bead 2. 5 designates a ring gasket of suitable and the rim 4.

Embracing the bead and rim is provided a' split ring or annular member 6 of channel or U-shape in cross-section, having a back or web portion I and substantially parallel flanges 8 extending therefrom. The ring is applied to the drum and head, and the free ends thereof are joined to se- Qcure'theassembly together. My invention is particularly directed to a means for removably securing said ring ends on the drum or container. In the form shown by Figs. 1 to 4, the ends of the split ring li are designed to abut, as at a, whensaid ring is secured in position on the con- Htainer.v A latch portion or member 9 spans the joint a and has one end thereof welded or otherwise' secured to one of the ring ends so es to form a continuation thereof. If desired, the portion '9 may be'formed as an integral partof the said i ring. Said portion or member 9 bears the same curvature as the ring 6, and is of Achannel or U-shape in` cross-section, having a back or web portion I0 `and extended substantially parallel flanges Il, the size of said member being suilicient' to overlap and receive the ring" ends therein. Said ring and latch member are preferably formed of a resilientA metal which will assist the manipulation thereof in applyingand removing the same 'to and from 'the' container. f

For the purpose of securing the ring against circumferential opening movement, the anges from, and the lugs I3 of the/latch portion projecting inwardly from the anges II thereof. ,f

The said projections'terminate in radial or transverse abutting edges substantially in line with the planes ofcontact b-b between the anges 8 and I I of the ring and latch members respectively, when assembled,.said edges thereby meeting in interlocking engagement at c. (See Fig. 4.) Suitable through-slots lor openings Il l lugs I3 in the openings of anges 8.

' in Fig. 1, to assist'in the engagement and dis The lugs I2 and I3 are preferably rounded and tapered away from their abutting edges as shown ber `9, said projection registering with and 'extending through the slot when the ring is closed.

Figs. '1 to 9 illustrate a modified form of my invention wherein the latch member 9a -may be hinged at 23 to one free end of the ring 6a to span the juncture a of the ring ends, when said ring is closed. `-In such form, lugs\24 on the back of the ring, and opposed cooperating interlocking lugs 25 on the back of the latch,member, may be subsituted for the 'lugs I2 and I3 hereinbefore described. Suitable openings 25 are provided in the ring and latch member for clearance of said engagement thereof, said rounded portions of eriflugs 24 and 25 whenthe same are engaged.

gaging lugs bearing or riding upon each other to enable the meeting of their abutting edges, as ill Ibe readily understood. Also, the rounded formation will assist in the entrance and exit of the lugs in and from their receiving openings I4 by engaging the walls thereof.`

Further means are provided to prevent separation 'of the ring 5, and-mcreparticularlx to resist the outward movement of the latch portion 9 from the ring end which it removably engages. Said means may be of various forms, but I prefer to provide struck-out lugs or projections I 5 'in the flanges 8 of the-ring, having terminal edgeslv I6 extending in a longitudinal direction with. respect to said flanges, at an angle to the abutting edges of the lugs I2 and I3. v

'I'he flanges I I of the -latch portion 9 are formed with struck-out lug-receiving sockets or recesses Il, one wall of each socket or recess being transversely inclined inwardly and toward the edge of the ange II, as at d. 'Ihe'terminal edges I6 of the lugs- I5 are correspondingly inclined for contact with said walls.

lIn securing the-ring 6 on a container or drum of the character stated, the ends thereof are urged together by any suitable means, and the latch member' 9 pressed into` operative engagement. The lugs l2 and I 3 cause their flanges to 'deflect'somewhat, due to the actionhereinbefcre described,l until said lugs engage in interlocking relation. The lugs I5 are deflected inwardly a slight amount and when in register with their respective recesses. I'I, ex outwardly into inter'- locking engagement therewith. 'I'he resiliency of the anges vI I will also assist the latter action.

'I'he resiliency of the ring and latch member, as well yas their interlocking parts will effect what may be termed a snap-on construction, whereby the parts are iexed upon engagement `and react to quickly and securely interlock to provide a strong and rigid connection.

To disengage the ring, a suitable tool or memb'er, as,for example, a nail or screw driver, may

' eo prying action between the backs of said laten and g be inserted in an opening I8 ofthe back or web ring with the tool, the lugs I2, I3, and I5 are readily disengaged. 'I'he rounded portions of the lugs I2 and I3 coact with the waYls of openings IIto separate the same by exing their flanges apart. Also,- the inclined walls d ofthe 'recesses I'IA ride outwardly on and separate from the inclined edges I5A of theirv lugs I5.'` A projecting inclined portion I 9 may be provided at the opening IB, to give additional bearingto the tool or member.'

Ii desired, means may be provided for the ap l plication of a sealing device, 'as thelead disc 2li.

.. in Fig. 2, said-means including a looped or. aperturedpunched out projection 2| on the face of ring 8 and a slot or opening 22in the latch memi' l i portion '28 for the insertion When the latch member 9a is closed on the.I

abutting ring ends, the transverse edges 21 of the lugs and 25 engage to prevent circumferential openingmovement of the ring. e lugs I5 are provided as before, and cooperate in interlocking relation with notches or recesses I1 on the latch: member 9a, to resist opening pivotal movement of said latch member. The free end of said latch member may also be providedwith a struck-up of a disengaging'tool or member as before. l

' From the foregoing, itwill be seen that I have provided by means of my invention, a split-ring construction for the purpose specified which lends itself to ready application to containers, and will be` rmly secured thereon.` Also, that a ring constructed in accordance with my invention may be frequently and repeatedly applied and removed without the danger of breakage or becoming inoperati-ve.

It will be undestood that various changes and modifications ar contemplated within the 'scope ofthe following claims.
